To all whom it may concern: I Be it known that 1, JOHN F. GAIL, a citizen of the United States, residing at in machines for forming links, and refers more particularly to a machine which is particularly adapted to make links of chains used in the construction of wire linle'bed fabrics. I i

Among the salient objects of the invenvtion are, to provide an automatic machine for cutting off lengths of wire from a'continuous wire supply and forming such lengths into the shape of links; to provide a machine of the type referred to in which the formed links are successively and autoinatically connected to form a continuous chain; to provide a machine in which the feeding forward of the wire from the continuous Wire supply is'eifected by the machine itself subsequent to a preliminary forming operation effected on the end of the continuous wire supply and prior to the severing of the link length; to provide a machine of the class described in which the operation of shaping the link is performed progressively upon the wire by successive forming mechanisms; to provide a machine of the class described in which the severing of the wire forming the link' is accomplished subsequent to a preliminary shaping operation performed upon the end of the continuous wire supply and before the link is completed; to provide a machine of the class described in which the wire from which the link is to be formed. is progressively advanced step by'step into the respective fields of the different forming mechanisms; to provide a machine of the class described in which the preliminary shaping operation performed upon the end of the continuous wire iscfl'ective in engaging the said formed end with the feeding mechanism; to provide a. machine of the class described in which the wire is advanced by the feeding mechanism initially as a part of the continuous wire supply, said part then being automatically severed and then advanced step by step to the mechanism for completing the llIlkS and connectlng them mto a contlnuous chain; to provide in a machine of the class described endless feeding mechanism having a uni-directional and intermittent move ment for progressively advancing the wire into engagement with the various mechanisms for operating on said wire; to provide a .machine which shall be extremely simple, rugged and economical in construction and very rapid and efiicient in operation, and, in general, to provide an improved machine of'the character referred to.

In order that the invention as herein after fully described and particularly claimed may be readily understood, I have based such description upon a preferred embodiment of the invention illustrated in the accompanying drawings, wherein Figure 1 is a rear elevation of such machine; Fig. 2 is a top plan view of the same; Fig. 3 is a front elevation; Fig. 4 is a vertical transverse section on the line 4i l of Fig. 1; Fig. 5 is a similar view on the line 55 of Fig. 3; Fig. 6 is an enlarged detail section taken on the line 66 of Fig. 5; Fig. 7 is a vertical transverse section on the line 7-7 of Fig. 2; Fig. 8 is a View partly in section taken on the line 88 of Fig. 7; Fig. 9 is a detail view of a link forming pin; Fig. 10 is an enlarged detail section on the line 10--10 of Fig. 9; Fig. 11 is a plan view partly in section taken on the line 11-11'of Fig. 8; Fig. 12 is a vertical section on the line 12-12 of Fig. 11; Fig. 13 is a horizontal section on the line 13-13 of Fig. 12; Figs. 14 and 15 are views respectively on an enlarged scale of associated parts shown in the left hand portion of Fig. 7 and Figs. 16 to 24 inclusive represent successive steps in the operation of the machine.

I-iaving reference in detail to the draw ings, the numeral 11 designates the machine frame upon which is journaled in suitable bearings the main shaft 12 provided with a drive pulley 13, the sprocket l4, and the beveled gear 15 which is in mesh with a similar gear 16 upon the shaft 17 which carries at its opposite end the crank disk I teeth 36 and 37 50 and leaving slight inclination to the line'of travel. 69

tov the diameter of and swept around the rier chain 26 which travels about the end guides 27 and 28. Each of the blocks is provided with a pair of eye forming pins 29 and 30.

Upon the shaft 12 is mounted a cam 31 for engagement with a roller 32 mounted upon one arm 33 of a lever, the other arm 34 of which bears against the roller 35 mounted upon a rack bar provided upon its two end portions with oppositely facing rack whereby the rack is reciprocated in active direction against the tension of the spring 38, it being returned by said spring in the inactive direction. The two toothed portions of the rack bar are in mesh respectively with pinions 39 and 40 which have their shafts 41 and 42 suitably mounted in the bearings 43-and 44 so as to provide for slight longitudinal movement of said shaft and pinions. Upon the upper face of each of the pinions bears the lower conical face of a slidably mounted thrust pin 45, said pins being downwardly pressed against the pinions by their springs 46 so as to normally hold the pinions and shafts in their lowermost position but permit the same to yield upwardly against the tension the springs 46. The lower end of each of the shafts 41 and 42 is stepped to provide a downwardly projecting fillet 47, the lower face of which occupies a plane below the general plane of the end of the shaft as clearly shown in Figs. 3 and 5. The line of travel of the pins 29 and 30 on the blocks 25 coincides substantially with the axes of the two shafts 41 and 42 and the drive of the chain 26 is so gaged as to bring a pin 29 to a position of rest with the axes of the shaft 41 and said pin 29 coincident and also with the axis of a pin 30 coincident with the axis of the shaft 42. In such position the upper ends of the pins extend upwardly above the lower plane of the fillets and the periphery of each pin is separated from the fillet by a space corresponding substantially the wireof which the links are to be made. v

The feeding mechanism receives the wire 49 supplied by the Wire straightener 48 and feeds the same into a position where its forward end'extends a slight distance beyond the spinner shaft 41 between the pin 29 and the fillet 47 .The spinning of the shaft 41 by its pinion 39 causes the terminal portion 49 of the wire to be engaged by the fillet 47 in Fig. 16, forming within said wire an eye the terminal portion" 49 at Z second reciprocation of the head 20 propels the chain 49 by'its engagement "with the pin 29, the forward end '49 of the wire being guided by the deflector 51 beneath the knife mechanismz, later to be described, until the chain pin 29, as indicated 26 forward and with it they wire and block come to rest, as shown in Fig. 3, with the pin 30 in axial alinement with the spinner 42I Thereupon the crank arm 52 of the crank disk 53 engages the end of the knife bar 54 and forces the same to the left, as shown in Fig. 4, the cam end face 55 of the same engaging the stud 56 to force the knife end 57 downward into horizontal alinement with the wire 49 whereupon the continued forward movement of the knife bar 54 severe the wire by the shearing action between the forward end 57 of the knife bar and the edge of the knife plate 58, the knife bar being returned to its original position after the cutting of the wire by means of the spring 59. The rear terminal portion 49" of the wire thus severed is now, by the rotation of the spinner shaft 42 by means of its pinion 40, swept around the pin 30, as indicated in Fig. 17, thus forming within said wire an eye 51, the terminal wire portion 49 retaining a position at an inclination to the line of travel as indicated.-

At the same time that the eye- 51 is being formed about the pin 30- and immediately after the wire has been severed by the knife, another eye 50 is'being formed'by the spinner 41, the wire being progressively oper ated upon in successive steps during its passage through the machine. Afterv havin had the two eyes 50 and 51 formed therein the link section, in the condition shown in Fig. 17, is moved forward at the next actuation of the carrier chain to the position shown in dotted lines in Fig. 18, with the pins 29 and 30 immediately to the rear of and longitudinally spaced equally from the pin 60 which is of larger diameter than the pins 29 and 30 and is provided near its lower end with a'transverse pin 61 the end of which protrudes slightly from the periphery of the pin 60 (Figs. 8, 9 and 15). The pin 60 has a square shank 62 which is secured by means of a screw bolt 63 in a stationary portion 64 of the machine frame. Guided within the member 64 is a reciprocating stripper bar 65 bifurcated in its lower portion to provide the downward projections 65 and 65*, one of which is disposed in front of and the other in'the rear of the pin 60, upon which latter the stripper bar 65 also slides, clearly indicated in Fig. 15. The stripper bar 65 is intermittently by means of the lever 66 one arm of which engages the top of said barand the other arm of'which carries a roller 67 engaged by the cam l68, mounted upon the main shaft 12, the return stroke of the bar being eifected by means of a suitably anchored coil spring 69 shown in Fig. 7,

Disposed immediately to the rear of the stripper bar 65 and the pin 60 in transverse alifnement therewith (Figs. 7, 11 and 15) is a slidably mounted block76 upon which and reciprocated ina downward direction j beneath the cap plate 71 is mounted a slidable plate 72, the block 70 having ears 73, 73 connected by the pin 74 carrying a roller 7 5 which engages the cam 7 6 upon'the shaft 12, whereby the block 70 is reciprocated in a forward direction, the said block being retraoted .by means of the suitably anchored spring 77. A pin 78 fixed in the block 7 0 extends through a slot 79 of the plate 12 so as to permit of slight relative independent movement of the said block and plate. Upon the two edges of the block 70 are fixed cam strips 80, 80 extending in a parallel direction and provided at their forward ends each with a cam face 81. A pair of arms 82, 82 are pivoted at adjacent points 83, 83 tothe plate 72 to swing in a scissorslike manner toward and from each other. These arms are curved upon their outer edges to correspond to the cam faces 81 of the strips 80 as clearly shown in Fig. 11. Upon their lower faces the arms are provided with a pair of pins 85': and 85 which, in the separated position of the arms, as shown in Figs. 11 and 15, are directly in alinement respectively with the pins 29 and upon which rest the coils of Wire forming the eyes 50 and 51, the lower ends of the pins 84 and 85 being in contact with the upper ends of the pins 29 and 30.

Beneath the plane of the block 70 and in advance of the mechanism just described is mounted for reciprocatcry movement a transfer plate 86 having a beveled face 87 normally disposed beneath the pin and with its'lower edge beneath the pins 29 and 30. This transfer plate 86 is carried by a bar 88 extending beneath the block and provided with a roll 89 engaging the cam 90 whereby the said plate is reciprocated to the rear being returned by means of the spring 91 mounted between the end of the bar 88 and the plate 92. This spring may be re-- inforced by a pair of springs 93, 98 anchored at one end to the cross pin 94, 9 1 of the fixed bracket 95, and at their other ends to a cross head 96 upon the end of a rod 97 extending within the bracket 95 and bearing against the rear end of the bar 88. When the partially formed link reaches the position shown in dotted lines in Fig. 18 with the eye portions of said link engaging the pins 29 and 30, the transfer plate 86 is moved by means of the cam 90 to the right engaging with'its beveled face beneath the link upon each side of the pins 29 and 80, transferrin the same therefrom upwardly on to the pins 84: and 85 of the arms 82. Thereupon the block 70 is moved to the left by its cam 7 6 carrying with it the plate 72 on account of the frictional engagement of the cam strips 81 and the bridging effect of the wire between the pins 84 and 85. When the-wire extending between the two pins contacts in its central portion with the pin 60 it can go no farther and bends at this point permitting the arms 82 to approach each other under the action of the cams 81, the speed of movement of the plate 72 lessening and the cam strips riding up the curved'outer edge of the arms and forcing the same inwardly. The effect is to bend the medial portion of the wire, as indicated in Fig. 18, about the pin 60 to form a large eye 98, the pins 84: and now occupying a position in advance of the pin 60 and closely adjacent each other, and the terminal portions 19 and 49 of the wire occupying a position substantially in parallelism as indicated in said figure in full lines.

Immediately in advance of the normal position of the transfer plate 86, as shown for instance in Fig. 11, is transversely mounted a slide 99 provided in its upper face with a slot having one wall 100 extending at right angles to the slide axis and the other wall 101 extending diagonally thereof. This slide is actuated by means of a bar 102 having its lower face provided with a diagonally extending shoulder 103 for engagement with the inclined wall 101 of the slot, the opposite end of the bar 102 being in engagement with the cam 104 by which it is actuated toward the left, its return being effected by the suitably anchored spring 105.

The movement of the bar 102 to the left' serves to move the slide 99 in one direction by the engagement of the inclinedsurfaces 101 and 103, the return of this slide being effected by means of a spring 106.

Mounted in advance of the path of the slide 99 (Fig. 7 is a vertical bracket 107 within which is guided a slide 108 having a head 109 with a narrow projection 110. This slide 108 is actuated in a downward direction by means of the lever 111 upon the opposite end of which is mounted a roller 112 which engages with the cam 113, the return of the slide 108 being effected by means of the spring 114. In the lower portion of the same bracket is mounted for reciprocatory movement a clencher bar 115, the upper end of which is provided with a cam face 116 coacting with the cam face 117 of a plate 118 fixed upon the bracket. The clencher bar is reciprocated upwardly by means of a lever 119 bearing against the lower end of said bar as shown, and providcd at the other end with a roller 120 in engagement with the cam 121, the return movement of the clencher bar 113 being oll'ccted by the spring 122.

While the link is held upon the pins 84, 85 und'till, as shown in full lines in Fig. 18, the forward ends 49 and 4-9" of the link project across the path of the slide 99 and plates 70 to their normal brought downward and the lower corner of the same engages the overhanging ends of the link and bends the same downwardly, as indicated in Fig. 21. The ends of the link at this time occupy a position immediately above the eye 98 of thepreviously formed link which rests upon the upper face of the plate 118 and with the coils of wire forming the eyes engaging the'edge of said plate as shown in Fig. 1 1, the link being held down in this position by the spring pressed foot 123 mounted in the head 109. As the corner of the head 109 bends the end of the link downwardly through the eye 98 of the preceding link, the clencher bar 115 is moved upwardly and the downturned ends of the link enter a recess 124 in the edge of said clencher bar. The upper end of the bar-is.

then deflected to the right by the engagement of the cam surfaces 116 and 117 whereby the bending of the link ends is continued about the slide 99, as indicated in Fig.

'22, The slide 99 is thereupon withdrawn;

and the further' upper movement of the clencher bar 115 completes the formation of; the hook, as indicated in Fig. 23, thereby ef fecting a permanent connection between the end portion of one link and the' terminal per bar (35 is depressed by means of its cam 68, the projection 65 engaging the terminal portions 49 and 49" of the link and the projection 65 engaging thehead of the link Y containing the eye 98 and stripping the linkoil of the three pins 8 1, 85 and 60, the accidental dislodgment of the link having been prevented by the protruding ends of the cross pin 61 over which the eye 98 is readily forced by the projection 65.

and 85 being howreleased the permitted to. spring back and follow the inactive position ready for the next link and, coinci dentally therewith, the'final clenching action of the bar 115 upon the link having lifted the eyes 50 and 51 out of engagement with the edge The pins 8 1 of the plate 118, the tension exerted uponthe last formed link by the PIBVlOlISly formed links wound upon the drum 125 causes the last formed link to jump forward until its eyes 50 and 51 engage over the rear edge ofvthe plate 118 beneath the spring presser foot 123. While resting in this position the head of the preceding link rests in a reciprocate transversely of said'channel is v a plunger 129 (Figs '3, 14. and 24-) having pl jects above the inclined surface of.

While have herein'set forth with a considerable degree of particularity the details of construction entering intoa preferred embodiment of the invention, it will be read ily understood by those skilled'in the art that'various modifications and changes in the form, construction and. arrangement may be adopted Without sacrificing the material advantages or departing from the es I claim:
